CARBU RETOR.

SPECIFICATION forming part of Letters Patent No. 474,838, dated May 17,1892. Application filed November 12, 1891. Serial No. 411;?397. (Nomodel.)

To aZZ whom it may concern.-

Be it knownV that I, JOHN W. LAMBERT, a citizen of the United States,residing at Ohio City, in the county of Van lVert and State of Ohio,have invented certain new and useful Improvements in Carburetors, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to a new and improved carburetor; and it has forits object to provide a device of simple construction which will beparticularly adapted for supplying air charged with the Vaporof gasolineor other liquid hydrocarbon to vapor or gas engines to be used as fuelor motive power thereof, as will be more fully hereinafter set forth.

The invention consists in the novel combination and arrangement of partsmore fully hereinafter described, and particularly pointed out in theclaim appended.

In the drawings, Figure l isa longitudinal section of a carburetor.sectional view on the line 2 2 of Fig. l, 3 is a similar view on line 33 of Fig. l.

In the construction shown I employ a reservoir a, preferably rectangularin shape, for containingthe liquid hydrocarbon and divide its interiorinto a suitable number of transverse compartments l) by means of thepartitions c, which extend from the top to the bottom of and entirelyacross the reservoir. These compartments communicate with each other bymeans of a vertical series of perforations c through one end of eachpartition, the perforations of one partition being near one side of thereservoir and those through the next or adjacent partitions beingnearthe opposite side of the reservoir, as clearly shown in Fig. 2. IThe topor cover d is secured to the reservoir by bolts or any suitable meansand is provided with an air-inlet pipe e, the lower end of which extendsnearly to the bottom of the reservoir. This pipe enters the reservoirthrough a suitable stuffing-box located at one corner of the cover, andit is made adjustable vertically through said stuffing-box for thepurpose of :regulating its extension into the reservoir. Thus adjustably supporting the inlet-pipe is advantageous in that it may beraised or lowered to suit the quantity of liquid in the reservoir, andthereby enable the effi- Fig.

Fig. 2 is a transverseciency of the device to be maintained until all ornearly all the liquid is used. The inlet-pipe ent-ers the firstcompartment at the opposite end from the communicating perforations inthe first partition, in order that the airl drawn in by the action ofthe engine, as will be hereinafter described, will pass through theliquid contained in said compartment and 6o over the surface of itbefore passing into the next compartment. This pipe extends a suitabledistance above the reservoir and may be provided with a suitable valve,if desired.

A domef is secured to Ithe top of the reservoir at the opposite end fromthe inlet-pipe, its lower-end openinginto the reservoir. The lower endof this dome has secured across it by any suitable means a tine orclosely-woven wire-gauze (,for a purpose hereinafterde- 7o of the domeand a metal clamping-ring 'L' by 75 means of bolts or other suitablemeans. This flexible head may be formed of rawhide,

leather, or any other suitable flexible material impervious toair andgas.

Gas from the upper end of the dome fis 8o supplied to the engine throughapipe j, which enters the dome near its upper end and is provided withsuitable regulating-valves, as desired.

The operation of niy'device is asI follows: 85

The reservoir being about two-thirds full of gasoline or other liquidhydrocarbon, air is admitted through pipe e, and as the lower end ofthis pipe extends below the surface of the liquid the air is drawnthrough the same, 9o

which insures its being charged thoroughly with hydrocarbon. Afterpassing across the surface of the liquid contained in the firstcompartment the air passes through the perforations in the tirstpartition and over the surface of the liquid contained in the secondcompartment, then through the perforations in the second partition nearthe opposite side of the reservoir, and so on in a zigzag course throughall the compartments in the reservoir '1 oo to the dome f. The gas orvapor is drawn through the compartments and from the dome f by theengine, each stroke of its piston causing the loose flexible head h tovibrate forcibly, which materially aids in expelling gas from the dome.As the gas is drawn from the dome air is sucked down the inletpipe belowthe liquid contained in the reservoir and passes through thecompartments, as before described, to the dome f.

The object of the gauze across the opening into the dome is to preventany dust or foreign substances that may enter the reservoir through theinlet-pipe from passing into the engine, and also to assist incommingling the air and vapor.

By this apparatus the air is thoroughly impregnated and eommingled withthe volatile vapor of the gasoline and a highly-infiammable gaseousmixture is produced thereby.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

In a carburetor, the combination of a reservoir, transverse partitionsin said reservoir provided with avertical series of apertures atalternate ends of each partition, a valved airinlet pipe entering thereservoir through the cover and extending below the level of the liquidin said reservoir, said pipe being adjustable vertically through thestuffing-box secured to the cover of the reservoir, a dome secured tothe cover ofA the reservoir at the opposite end from the inlet-pipe, itslower end opeuinginto the reservoir, a flexible head closing the Lipperend of said dome, and a valved outlet-pi pe entering the dome betweenthe ganze and the flexible head, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN W. LAMBERT.
